Thyristor modules MT3, MT4, MT5
Power SRC dual thyristor modules MT AS ENERGITM are a monolithic design with two semiconductor thyristors (type thyristor-thyristor), operate in DC and AC circuits with loads from 115A up to 1250A and reverse pulse voltages up to 6500V.
Connection diagram of modules: MT3 – half-bridge; MT4 – common cathode circuit; MT5 – common anode circuit.
High energy-thermocyclic resistance and reliable operation of low-frequency thyristor modules of MT when switching high currents is achieved due to their design features and stable parameters galvanic separation:
- the dielectric strength of the insulation between the potential-free base and the leads reaches the mark 3600V under normal climatic conditions and 1500V at high humidity;
- housing is made of non-combustible thermopolymer;
- the dielectric strength of the insulation between the main and control leads reaches the mark of 2500V under normal climatic conditions and 1500V at high humidity;
- the insulation resistance between the potential-free base and the outputs under normal climatic conditions is at least 50МОм and no less than 5МОм at high humidity;
- insulation resistance between main and control leads under normal climatic conditions is at least 1000МОм and no less than 100МОм at high humidity;
Thyristor modules MT3, MT4, MT5 have a clamping design, mounting with screws through the through mounting holes in the housing. The wires are fastened with nickel-plated terminals, under which the test points for measuring the pulse direct voltage are placed. Main leads are on the top of the case and are numbered 1, 2, 3. Control leads are marked on the diagram as G1, G2. Additional cathodes are marked on the diagram as K1, K2.
When mounting thyristor modules, special attention should be paid to the tightness of the mating surfaces – concavity more than 0.03 mm is not allowed.
To mount additional cooling (radiators or coolers are used), mounting holes are provided in the housing of the thyristor potential-free modules. A special thermally conductive substrate lubricated with thermal paste must be used between the module and the cooling element.
Thyristor modules MT3, MT4, MT5 are used in various power installations - power and control units, power regulators, AC regulators, inverters, motor starters and controls, temperature controllers of blast furnaces or chemical processes, welding equipment, etc.
Our modules are offered in several dual and single device topologies for almost all phase control or rectifier applications.

Recommendations for mounting power modules
Heatsink and Surface Specifications, Preparation
In order to ensure good thermal contact and to obtain the thermal contact resistance values specified in the datasheets, the contact surface of the heat sink must be clean and free from dust particles. It is useful to clean the mounting surface of the heat sink with wipes and an alcohol cleaner, e.g. isopropanol, right before the mounting process. The following mechanical specifications have to be met:
– Unevenness of heat sink mounting area must be ≤ 50μm per 100 mm
– Roughness Rz: < 10 μm
– No steps > 10 μm
Heat sink surface specification
Applying Thermal Paste
Recommended to use stencil printing in order to apply thermal interface material. Recommended to use thermal paste thickness in the range from 50 μm to 100 μm. Applying thermal paste by means of roller is not recommended for mass production as reproducible of an optimized thermal paste thickness cannot be guaranteed.
Mounting torque on heat sink MS
To secure power modules, the use of steel screws in combination with suitable washers and spring lock washers or combination screws is strongly recommended. The specified in datasheet torque value must be observed.
A pre-tightening torque and retightening to the given torque value is recommended. For the screwing process the speed has to be limited and soft torque limitation is recommended to avoid torque peaks, which may occur with pneumatic screwdrivers.
Example of mounting order
The screws must be tightened in diagonal order with equal torque in several steps until the specified torque value MS has been reached.
